The NATIONAL MARKER N220715 is a zinc-finished lag screw eye designed for heavy-duty fastening applications where a threaded anchor point with an integral loop is required. Manufactured from steel with a zinc coating for corrosion resistance, this screw eye measures 3/8 inches in diameter and 8 inches in length. The lag thread profile allows the fastener to be driven directly into wood substrates without a pre-drilled pilot hole in softer materials, though a pilot hole is recommended for hardwoods. It is commonly specified by electricians, plumbers, HVAC technicians, and general trade contractors for anchoring conduit, pipe hangers, guy wires, and support cables.
This lag screw eye suits residential and light commercial installations where a secure threaded loop anchor is needed in wood framing, beams, or blocking. The 3/8-inch shank diameter and 8-inch length provide deep thread engagement for higher pull-out resistance compared to shorter variants. Typical applications include suspending equipment, routing cable, and securing support lines in attic, basement, and mechanical room environments.
Designed as a standard lag screw eye for use in wood framing applications; consult load ratings and applicable building codes to confirm suitability for your specific installation.
Installation is performed using a wrench or bit driver engaged through the eye loop; do not use an impact driver at high torque settings as this can distort the eye. A pilot hole is strongly recommended in hardwood or dense lumber to prevent splitting and ensure straight thread tracking. Follow applicable building and mechanical codes when using this fastener for equipment support or suspension.
